SCIENCE CONTENT STANDARDS: Cladisticules FOR GRADES 9-12 National Science Content Standards Science as Inquiry: A X Physical Science: B Life Science: C X Earth and Space Science: D Science and Technology: E Science in Personal and Social Perspectives: F History and Nature of Science: G X Some specific National Science Content Standards that pertain: Science as Inquiry (Content Standard A) Identify questions and concepts that guide scientific investigations; design and conduct a scientific investigation; recognize and analyze alternative explanations; communicate and defend a scientific argument. Life Science (Content Standard C) Biological Evolution-Species evolve over time; the great diversity of life today is the result of 3.5 billion years of evolution; the millions of species of plants, animals, and microorganisms alive today are all connected through descent from common ancestors; biological classifications are based on how organisms are related; organisms are classified into a hierarchy of groups and subgroups based on similarities that reflect their evolutionary relationships. History and Nature of Science (Content Standard G) Nature of Scientific Knowledge-Scientific explanations must meet certain criteria; because all scientific ideas depend on experiment and observational confirmation, all scientific knowledge is, in principle, subject to change. FOR GRADES 9-12 California Science Standards Cell Biology Genetics Ecology Evolution X Physiology Some specific California State Standards that pertain: Concept 8: Evolution is the result of genetic changes that occur in constantly changing environments f) Students know how to use comparative embryology, DNA or protein sequence comparisons, and other independent sources of data to create a branching diagram (cladogram) that shows probably evolutionary relationships.
